Bed supporting device

Abstract

A bed supporting device adapted to be installed to a bottom seat of a bed includes a leg unit; a first link board connected to an upper end of the leg unit, and formed with a first through hole; and a second link board for connection to the bottom seat, installed on the first link board and formed with a second through hole corresponding to the first through hole; wherein, either the first or second through hole is elongated such that a fixing screw can extend through the first and second through holes in the first and second link boards for coupling a fastener, thereby immobilizing the first and second link boards.

What is claimed is: 
     
       1. A bed supporting device adapted to be installed to a bottom seat of a bed, comprising:
 a leg unit; 
 a first link board connected to an upper end of said leg unit, and formed with at least one first through hole; 
 a second link board adapted to be connected to the bottom seat of the bed, installed on said first link board, and formed with at least one second through hole corresponding to said first through hole; and 
 an anti-slippery unit including a cushion plate disposed at a bottom end of said leg unit and formed with a screw hole; 
 wherein, either said first or second through hole is elongated such that a fixing screw can extend through said first and second through holes in said first and second link boards for coupling with a fastener, thereby immobilizing said first and second link boards; 
 wherein after assembly, a horizontal plane of the bottom seat of the bed and said leg unit define an acute angle in a clockwise direction which is lesser than 90 degrees or an obtuse angle in an anti-clockwise direction, which is greater than 90 degrees; 
 wherein said leg unit extends inclinedly and outwardly from the bottom seat of the bed due to said acute angle or said obtuse angle; 
 wherein said anti-slippery unit further includes an anti-slip pad disposed below said cushion plate opposite to said bottom end of said leg unit so as to be contact with a support surface and a fastener screw extending threadedly through said screw hole in said cushion plate for fastening said anti-slip pad; and 
 wherein each of said first and second link boards has a coupling face formed with a shallow groove pattern to provide friction between said each coupling face after coupling of said first and second link boards. 
 
     
     
       2. The bed supporting device according to  claim 1 , wherein said first through hole in said first link board is elongated in cross section while said second through hole in said second link board is circular in cross section. 
     
     
       3. The bed supporting device according to  claim 1 , wherein said first through hole in said first link board is circular in cross section while said second through hole in said second link board is elongated in cross section.
